The picture is unclear so I cannot really help. I'm sure I could if it was clearer though.
Do 4x5, that is all you need to do, did you learn fractions in elementary?
Answer:
The value of x is 27
because 2 times 27 equals 54 minus 7 equals 47
Both of them together have 690 because you subtract 152 from 421 so...
421-152=269
Then add 269 to 421
421+269=690
